A. LA ToRRAcA HAIR WAVING APPLIANCE Filed June 14, 1944 Patented May 1, 1945 'UNITED STATES PATENT OFFICE HAIR WAVING APPLIANCE `Anthony Torraca, Newark, N. .I.` Application June 14, 1944, Serial No.- 540,177 2 claims. (fol. isz-ss) This invention relates to improvements in hair waving appliances; and the -invention has reference, more particularly, to an improved and simplied` device adapted especially for use in waving hair by the method known to the art as the cold wave process which avoids the necessity for use of heatand attendant discomfort to the subject which the use of heat involves.

This invention has for an object to provide a hair waving appliance comprising a base clamp and a mandrel removably mountable thereon; said base clamp being of very simple and compact construction, having a minimum of manipulatable parts, whereby the Same can be easily and quickly manipulated and applied in use, and which, when applied to the subjects head, is of minimum weight and bulk. l

The invention has for further objects to provide a novel constructionY of hair waving appliance comprising a base clamp for gripping, in use, a selected tress of the subjects hair as closely as possible to the scalp, whereby to hold such tress subject to preliminary treatment andmanipulation by the operator, while at the same time functioning to guard or protect the subjects scalp during such treatment; said clamp having novel means for latching its pivoted clamp bar in holding relation to 4the tress of hair, which means is self-adjusting to automatically accommodate the hair gripping and holding position of said pivoted 30 clamp bar according to the amount or quantity of hair in the tress thereof selected `for treatment; said 'base clamp being further provided at CA'I l ing parts.

As shown to best advantage in Figs. 3 to 5 inclusive, the base clamp member of the hair waving appliance according to this invention comprises a main body l'of suitable width and length. Intermediate its` ends, said main body I is cut away along one side to provide a longitudinally extending portion of approximately onehalf the width thereof` and of reduced thickness adapted to constitute a stationary clamp bar II.

Upstanding from the respective end portions of said main body, perpendioularly to the plane its ends with upstanding transverse bifurcate posts, the spaced arms of which dene upwardly open bearing notches, and the inner sides of said arms carrying arcuate leaf-springs for gripping and retaining the trunnions of a mandrel upon which the tress is wound after preliminary treatment, when said trunnions are entered in said 40 bearing notches so as to operatively couple said mandrel to the base cla-mp. l

Other objects ofvthis invention, not at this time more particularly enumerated, will be understood from the following detailed description `of Athe same. l

An illustrativeembodiment of this invention is shown in the accompanying drawing, in which:

Fig. 1 is an end elevational view of the base clamp member of the appliance as operatively applied to a tress of hair at a point close tothesubjects scalp, whereby the tress may extend therefrom subject to treatment by the operator; and Figi@ is a transverse4 sectional view of theja'pthereof, are transverse bifurcate posts I2, the

spaced opposed arms I 3 ofwhichdefine upwardly open bearing notches I4, which are aligned t with the central longitudinal axis of saidmain body. Aillxed to the free end portions of said arms I3, to extend downwardly therefrom, respectively into and along opposite inner faces of the sides of said notches I4, and thus in opposimovable clamp bar corresponds in thickness and length to the thickness and length of the stationary clamp bar I I, and is adapted to be swung into and out of the cutaway side of said main body I0, so as to oppose and cooperate with the inner edge portion of said stationary clamp bar when inswung toward the latter.

The top face of said movable clamp bar I8 is provided with a longitudinal guideway channel I9 which extends from its free end toward its pivoted end. Slidably mounted in saidpg'uideway channel I9 ls a latch bolt 2U,`the outer` side of the free end portion of which is providedwith an inclined pliance showing thetreated tress of hair wound 55 wedging face 2|. The end portion ofthe main body Ill, opposite to that to which said movable clamp bar I8 is pivotally connected, is provided with a longitudinally disposed latch bolt receiving -socketl 22, which is opposed to the free end of said movable clamp bar-I8 when the latter is inswung into cooperative relation to said stationary clamp bar II, and which is adapted to receive engagement of said latch bolt 20, when the same is projected from the end of the thus in-swung movable clamp bar I8. The means for retaining the latch bolt 20 in operative assembled relation to said movable clamp bar, in one illustrative embodiment thereof, comprises a headed keeper stud 23 which is aixed to the movable clamp bar to extend through a longitudinal slot 24 with which the body of said latch bolt 20 is provided. At its inner or rearward end, said latch bolt 20 is provided with a raised boss 25 or other suitable means affording a nger-piece to aid manipulation thereof.

Detachably mountable on the base clamp member is a mandrel 26 having trunnions 21 respectively projecting axially from its opposite ends. The body of said mandrel 26 is of a length to i'lt and engage between the posts I2 of the base clamp member, and is preferably of the shape shown in Fig. 6, being of maximum diameter at its end portions and tapered from said end portions toward its mid-portion which is reduced in diameter and cross-sectional area. Pivotally connected with one end portion of the mandrel 26 is a hair gripper member 28 which substantially conforms to the side contour of the mandrel, when swung inwardly along a side thereof.

In the use of the appliance for treating a tress of hair by a cold wave method, the tress T (see Fig. 1) to be treated is separated from the mass of the subjects hair and the base clamp member is applied thereto. To this end the movable clamp bar I8 is released and swung outward to open position (see dotted representations' thereof in Figs. 3 and 5), whereupon the base clamp member is applied close to the scalp of the subject, adjacent to the base of the tress T, and so that the latter may be laid across the inside gripping edge of the stationary clamp bar II,

so as to be disposed between the latter and the open movable clamp bar I8. The tress T having been thus disposed, the movable clamp bar I8 is closed to grip the base of said tress close to the subjects scalp, and is thereupon latched for retention in such gripping relation to the tress by sliding forward the latch bolt 20, whereby to enter its projected end in the receiving socket 22 of the main body I8. In thus engaging the main body I0, the inclined wedging face 2I of the latch bolt 28 will abut a contiguous side of said receiving socket 22, and will not only rmly pinch the engaged hair between the opposed edges of the stationary and movable clamp bars II and I8, but, owing to its inclined face, will automatically adjust the gripping position of the movable clamp bar to that best adapted to accommodate and hold the particular amount or quantity of hair making up the base portion of the tress T.

When the base clamp member is applied to the tress and secured in the manner above set forth, said base clamp member will be positioned and retained close to the subjects scalp, not only so as to segregate the tress T from the mass of the subjects hair, but also so as to protectively cover ment by the operator pursuing a cold wave method, which treatment comprises combing or brushing out the extending tress and thereupon applying to and wetting the same thoroughly with a treating liquid of suitable chemical character istics adapted to facilitate setting of a wave or curl therein after the tress is Wound upon the waving or curling mandrel 26.V

To wind the tress upon the waving 0r curling mandrel 26, the hair gripper member 28 is swung or opened out, whereupon the free end portion of the tress T is laid over the mid-portion of said mandrel vand said hair gripper 4member 28 closed thereover to grip and hold such tress end portion. Thereafter, the mandrel 26 is rotated to wind up the tress T thereon and about the gripper member 28, and so as to carry said mandrel to the base clamp member. As the mandrel reaches said base clamp member, mandrel trunnions 21 are respectively entered in the respective notches I4 of the posts I2, and are pressed inwardly so as to ride over the opposed arcuate leaf springs I5 and beyond the bowed mid-portions of the latter until stopped at the bottoms of said notches. It will be obvious from an inspection of Fig. 7, that said springs I5 will releasably retain the trunnions 21 against accidental outward displacement from the notches I4. thereby holding the mandrel and the tress wound thereupon in attached relation to the .base clamp member, so that the tress is retained in the described Wound relation to the appliance.

The appliance as thus operatively applied to the subjects hair and head is allowed to so remain a suiiicient length of time necessary for eiective action of the treating solution in setting the wave or curl in the tress, after which the appliance may be removed, and the waved or curled hair may thereupon be dressed by the operator to produce such style of coiffure as may be desired.

In carrying out the cold wave method, it is desirable to bring the treating solution in contact with substantially the entire length of the tress under treatment, and then to wind the treated tress as close to the head as possible. The appliance according to this invention is especially designed to attain these ends, since the clamp bars are of minimum thickness, and the means for receiving and holding the mandrel 26 in mounted relation to the base clamp member is such that said mandrel may be brought very close to clamp bars of said base clamp member.

It will be understood that the base clamp member and the mandrel may be made of any suitable material, and especially, except for the springs I5, of non-metallic material, such e. g. as plastics and like materials which are not likely to be deleteriously effected by the treating solutions employed in cold wave methods of hair treatment.

Having now described my invention, I claim:

1. A hair waving appliance comprising a base clamp member having a main body cut away along one side intermediate its ends to provide a stationary clamp bar portion, said main body having transverse bifurcate 'posts upstanding from its respective end portions to provide outwardly open notches, a detachable mandrel member, said mandrel member having trunnions projecting from its opposite ends for connement within said post notches, whereby to support the same upon and between said posts in closely spaced relations to said main body, yieldable detent means axed to the opposite interior walls oi said post notches forrelea`s-" socket, and said latch bolt having an inclined ably holding the mandrel trunnlons against clamp bar pivotally attached by l one end to one end portion of said main body, whereby to be swung into and out of the cut away side of said main body in opposition tothe inner edge of said stationary clamp bar portion thereof, a latch displacement from said notches, a movable outwardly facing wedging portion at its receiving socket engaging end for self-adjustingly securing said movable clamp bar in gripping relation to a tress of hair disposed between the latter and said stationary clamp bar. 2. A hair waving appliance as deiined in claim 1,wherein said yieldable detent means cooperaassembled relation to said movable clamp bar, a
